described, claimed, and illustrated in the ac- Y i companying drawings, in which:

Fig. 1 shows a fragmentary top plan view of a row boat equipped with a pair of my improved oars.

Fig. 2 shows a "5 thereof.

Fig. 3 shows a top plan detail view of the supporting member, as employed as a means of attaching my improved oars to a row boat.

Fig. l shows a side elevational fragmentary detail view of my improved oars, and the supporting members employed as a means of attaching same to a row boat.

Fig. 5 shows a fragmentary sectional view taken on the line 5-5 of Fig. L

"5' Fig. 6 shows a modification of my improved blade member as embodied in my improved device.

As here embodied my improved device comb prises a supporting member consisting of "'fl a pair of base members 10, attached to the sides 11, by the brackets 13, extended therefrom, as clearly shown in Figs. 1 and 2, of the accompanying drawings. The brackets 14.- and 15, are pivotally attached as at 16,

" 17, and 18 and 19, respectively, by threaded members, set screws or the like, carried in the lug elements 20 of the base members 10. rlhe extremities of the threaded members 16, 17, 18, and 19, engage in apertures formed in the i" extremities of the brackets 14 and 15, and are secured therein, as may be desired by the nuts 21, threadedly attached to the threaded members 1G, 17, 18, and 19. rlhe above described construct-ion being such as will permit the said brackets 14 and 15 to be pivoted, as may be desired for the purpose as hereinafter set forth.

The handle member 22, is provided with a free extremity 23, formed or shaped so as transverse sectional View JU to provide a grip, such as usually used for the purposeI of gripping or holding an oar as amea'ns." of rowinga'boat with4 thel saidy ear. irlhfe plate member 24, is adjustably attached to'the handlemember 22, by'` the bolts 25, adapted'to'engage in anyof the desiredle apertures 26,` formed in the 'handle memberv 22,and'in the plate member 24, as a means of"adjusftably attaching the plate member 2d to the handle member 22. The plate mem-- ber'24l`` isj` 'providedwithy notches 27, adapted 6U to engagein similar shaped protruding elements 'of the handle member 22', asa means ofsecuring the said engagement of the plate member'24 with' the'handle vmember. 22,.

Theplate member 2et-isfprovided withay lug element 28,"haf'ving an aperture adaptedA to,l receive they pin v29,' -pivotally attached, as atf30`to the e'i'rtendedl portion of the above mentioned brackety 15'.` .Tlie'pin 29, haspiv- .Y

otally attached at 'its free extremity, a lock- '35 ing inemberhas a means of pivotally secur-` ing't'he handle member 22 to the bracket l15.

The blade member'32, is provided with a'- free extremity '33,formed or shaped, so as to provideva' blade,such as usually'used for the purpose' of propelling or rowing a boat', when thelsaidbladefis vpulled through the,- water.' The bladefmember 32,Y is similarly pivotally attached, asis' thehandle member Y 22,"t'o the free extremity of'thet'a'bvemenet tioned bracket"`14, as hereinbefore described; and set forth,-"similar 'elementshaving the same reference numerals inthe accompa'ny ing drav'vings VAVA A The handle member'22isipivotally attache'd to thebladejmember 32,',i1itermediate the brackets 1li-fand 15,'by'a threadedmeniber si @mieu in thjeibmketsa-ad se, attached" to theb'lade member' 32' Iand handlefmemberfV 'i 22, respectively. l j

The abo've described construction being such'l as willperm'itfthe rowboat 12 to be rowed'. ,"It being 'understoodthat .the handle"L memberI 22,` andthe blade 'member 32," may vbey adjustablylattached to thefjbrvackets 15 and 14, i: respectively, as a means :of -increasing the`.- movement ofthe'blade member 82`relative te thev handle" member 22. It' vbeing obvious thefabove described construction is suchA x pivotally attached, as at 42, to the bracket 43,

attached tothe blade section.y 32. The threaded members 44 are adj ustably attached to the extended extremity of the rodV 38.

lThe above described construction being such as will securely hold the supplementary blade section 37 in any desired relative position to,

the blade section 32. The supplementary member section '37 may be p ivotally mounted on the brackets 14 and 15, and the both blade sections and 32" may be used as the blade member' 32.

Y It will Lbe understood that one or more pairs ofmy improved oars are used, as is customary practice in devices of this particularx nature.

Having thus described my invention, what' I claim las new and desire to protect by Letters Patent of the United States is as follows l. In a device of the class described, a blade member comprising a supplementary blade section, a blade section pivotally connected to the supplementary section and means for holding the saidr sections lin fixed adjusted positions, comprisinga rod pivotaly attached to the supplementary blade section, and means for pivotally and adjustably holding said rod to the blade section.
